Answer

Zinc Sulphate – Displacement
$Zn(OH)_2 + H_2SO_4 ⟶ ZnSO_4 + 2H_2O$
Ferrous sulphide – synthesis
$Fe + S ⟶ FeS$
Barium sulphate – Precipitation
$BaCI_2+H_2SO_4 ⟶ BaSO_4 + 2HCI$
Ferric sulphate – Oxidation
$Fe + H_2SO_4 ⟶ FeSO_4 + H_2$
Sodium sulphate – Neutralisation
$2NaOH + H_2SO_4 ⟶ Na_2SO_4 + 2H_2O$
